Modular overcurrent circuit breakers of the Ex9BN series are universal devices for all types of applications meeting the high standard requirements for domestic use according to EN 60898 in the rated current range from 1 to 63 A. The rated short circuit breaking capacity Icn is 6 kA. In any case, Icn applies to all breaker versions, i.e. to rated currents up to 63 A and tripping characteristics B, C, D.

The overcurrent protections of the Ex9BH series are available in 1, 1+N, 2, 3, 3+N, 4 - pole variants, where the pole width corresponds to one module - 18 mm. Tripping characteristic curves: B, C, D. In terms of mechanical parameters the Ex9BH and Ex9BN series are fully compatible.

They can be combined with a wide range of accessories, including auxiliary contacts, auxiliary tripping contacts, rising, undervoltage and overvoltage trip units or residual current blocks. Various combinations of accessories are possible. These combinations are limited only by the total number and not by the type of accessories - all components fit together. Up to three auxiliary contact units or tripping auxiliary contacts and up to two trip units can be fitted.
